CalLUING-PFRESS.

Specification forming part of Letters Patent No. 55,334, dated June 5, 1866.

To all whom it may concern:

Be it known that we, M. H. MERRIAM and E. L. NORTON, both of Charlestown, inthe county of Middlesex and State of Massachusetts, have invented an Improved Gementiugor Grlu-A ing Press; and we do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of our invention sufficient to enable those skilled in the art to practice it.

The invention relates to that one of a series of operations converting skins ot' leatherinto shoe-bindingA ribbon in which the strips of leather are cemented together to form a continuous ribbon.

More particularly the invention relates to the construction of a press by which the ends cemented. together are held inv position until they are firmly united.

The invention consists in combining` with the bed and platen of the press guides placed one upon each side of the platen in such manner that the, two strips as they are brought to.- gether in the press may be readily placed in line by bringing the corresponding edges of both pieces against the respective guide-pieces, with the ends to be united under the platen, the result being that the strips, after the action of the platen, and when withdrawn froml the press, will be in perfect or practically perfect line one with the other, also, in having upon the face of each platen of a series of presses an identifying die or mark, which, by each action of each platen, is struck into the strip; also, in so applying the platen that it may yield to the inequality in the thickness of the united ends, so that pressure may be brought equally over the whole surface under the platen, causing uniform adhesion of the surfaces brought together.

The drawings represent a press embodying the invention.

Figure l shows a plan; Fig. 2, afront elevation; Fig. 3, a section y taken transversely through the center of one of the platens.

a denotes the bed, making up, with the posts b and cross-beams c, the frame for the support of the mechanism. 4

The drawings show two platens, d, jointed to the lower ends of followers c, which are pressed down by levers j and carried up by springs g, as will be readily understood. On the bed-piece u, and upon each side of the platen, is a guide-piece, h, the two opposite guide-pieces or their inner edges being in line, as seen in Fig. 1. These guides may be placed upon one or both sides of the platen, and each two in line may be made as one piece extending through the press.

In the operation of thepress oneof the strips is laid upon the bed with one edge along and against the edge of one of the guides, and with its end to be cemented under the platen. The other strip is then placed on the bed with its edge against the corresponding guide upon the opposite side of the platen, and with its cement-applied end under the platen and over the end of the other strip to which it is to be united. This brings the two pieces into line, and in such manner that after the platen is brought down upon them to press and keep the adhering parts together until they are firmly united, and the strips thus united are removed from the press, the two parts shall be as one piece, with their corresponding edges inline. In carryingon the operation of cemen ting a series of presses are arranged inline, as shown with the two in the drawings, and the operator, having joined two strips and brought the platen down upon them, proceeds with the next strip to the nextplaten, and so on through the series, the number of platens or presses being such that upon reaching the last one the strips in the rst shall have become so firmly united as to permit them to be removed from the pressure of the platen, the strip being passed through the press un til its end is brought Linder the platen and in position for the application of a new piece.

In the manufacture of shoe-bindingwe iind it convenient, and oftentimes necessary, to be able to identify the manufactured article with the operator under whose, hands the same was formed into ribbon. For this purpose each of the series of presses in line is attended by one person, and each platen of the series has upon its lower surface a corresponding identifying die, mark, or number peculiar to the series, as seen in Fig. 3, which is a view of the face of one of the platens of the series each of which has the corresponding mark, which, by the pressure of the platen, is struck into the surface of the bindingaat each joint, thus enabling any imperfection in the article produced to be traced to the attendant by whom the same was made. In this way we secure carefulmanipulation and correspondinglyr perfect results.

Each platen is hung or jointed to the follower in such manner that it may swivel laterally and longitudinally, this being effected by hanging the pins on which the platen turns in elongated slots or bearings i in the follower, the extent of lateral rocking movement of the platen being controlled by stop-plates k. By this means the surface of the platen is made to bear uniformly over the whole surface of the end of the stripbeneath it, though such strip or strips may be of uneven thickness.

We claim- 1. In combination with the platen audits bed,

a guide-piece upon each side of the platen for bringing the strips to be united into line, substantially' as set forth.

2. The employment of an identifying-mark upon each of a series of platens, as and for the purpose specified.

3. Hanging the platen so that it may swivel to accommodate the acting `face of the platen to the surface of the strip beneath it, substantially as set forth.

In witness whereof we have hereunto set our hands this 24th day of November, A. D. 1865.
